you're moving through this discussion exactly backwards; the current
proposal stems from the observation that "for-loop plus generators" in
today's Python does in fact provide a block implementation that solves
many use cases in an elegant way.

PEP 340 builds on this, sorts out a couple of weak points in the current
design, and adds an elegant syntax for most remaining use cases.
